Title: Apparatus for slicing material to be cut, preferably pieces of meat, especially sides of lox, into slices
Inventor: SCHMIDT HANS J
IPC: B26D3/00
Filed: 1991-03-08
Abstract: Abstract:     An apparatus for slicing material to be cut, preferably pieces of meat, especially sides of lox, into slices, has a cutting station and a transport device which guides the material to be cut through the cutting station.  The transport device comprises a track element, of which the support surface for the material to be cut is formed of adjacent track segments, with a pre-determined number of track segments being formed as carriers for the material to be cut, which can be moved in increments, relative to the adjacent track segments, by means of a drive device.     The drive device comprises elements for vertical drive and for horizontal drive of the movable track segments.     Each track segment is a strip that extends across the length of the track element.

Title: Filter cleaning apparatus
Inventor: BLACK BRENT C
IPC: B01D24/00
Filed: 1991-04-02
Abstract: The invention comprises an improvement in a cleaning apparatus particularly useful for filters. A mechanism drives a hood into position adjacent partitions. A sealing member is selectively actuated to seal off at least one such compart-ment for cleaning while the remainder of the filter remains in service. Sealing is accomplished by interaction between the hood and the partitions. The invention also relates to techniques for selectively bringing the hood into contact with the partitions, and a construction of the hood and a media support plate which allows flexibility to lift and scour the filter media using a gas to dislodge impurities, coupled with a liquid backwash involving drawing filtered water back through the media to carry away the impurities out of the filter.

IPC: B62D5/093
Filed: 1991-06-12
Abstract: A fully hydraulic steering arrangement for vehicles is proposed, with an hydraulic pump (2) that is connected to a control valve (4) operable by a steering handwheel (5), a steering motor arrangement (8) and a steering metering device (7) which controls the volume of hydraulic fluid to be fed to the steering motor arrangement (8) by the control valve (4).     In a steering arrangement of this kind, the physical effort expended by the driver during manoeuvering shall be reduced using simple means.     To that end, an actuating device (13) is provided, which on operation arrests the metering device (7) mechanically with the aid of a brake device (15) and in this manner prevents the steering metering device (7) being actuated by the hydraulic fluid, and with the aid of a short-circuiting valve (14) produces a short-circuit for the hydraulic fluid for the steering metering device (7).

Title: Apparatus and method for angle measurement
Inventor: HILL JERRY M
IPC: G01C1/00
Filed: 1991-07-17
Abstract: Apparatus is disclosed which includes two side-by-side planar light sensors.  A light stop is spaced from one light sensor in position to stop or shade half of the light sensor surface from a projected light beam when the beam is orthogonal thereto.  The other light sensor is completely exposed to the projected light beam.  The one light sensor is exposed to more or less of the light beam dependent upon the beam's departure in one direction or the other from orthogonality to the plane of the one light sensor.  A ratio of the output from the one light sensor to the output from the other provides beam angle information relative to the plane of the one light sensor.

Title: Opti-mechanical displacement indicator with high sensitivity
Inventor: POPENOE CHARLES H
IPC: G01L5/00
Filed: 1990-01-23
Abstract: In an indicator for visually displaying extremely small displacements between two points within a structure, a change of color visible through an indicator window (26) occurs during a preselected portion of a predetermined displacement within the structure. The color change occurs due to an increase in thickness of a light-absorbing fluid (42) in the central area of a clear, flexible indicator means separating a colored portion from the indicator window. Substantially no light-absorbing fluid is permitted to enter the central area until a preselected displacement has occurred since the colored portion is firmly, resiliently biased against the indicator window until that amount of displacement has occurred.  Thereafter, light-absorbing fluid is permitted to enter the central area. This device concentrates visual indications of displacements into limited segments of an overall displacement,

Title: Process for continuous production of bioactive calcium phosphate particles
Inventor: SHIRKHANZADEH MORTEZA
IPC: C25B1/18
Filed: 1992-08-07
Abstract: Abstract Calcium phosphate crystal particles are formed electrochemically and continuously on a conductive conveyor belt, passing through an electrolyte containing Ca- and P- bearing ions.  A sufficient cathodic current is passed through the electrolyte to the conveyor belt, which results in nucleation and crystallization of calcium phosphate crystals on the conveying belt.  Calcium phosphate crystals, formed on the conveying belt, are continuously washed, dried and removed from the conveying belt.  The process of this invention permits continuous production of calcium phosphate crystal particles at a high rate and in a commercially viable manner.

Title: Signal routing device
Inventor: JENKINS RICHARD M
IPC: G02B6/12
Filed: 1991-12-02
Abstract: A signal routing device (10) incorporates a multimode beamsplitter waveguide (20) connected by a set of parallel relay waveguides (22) to a multimode recombiner waveguide (24). Each relay waveguide (22) contains a respective electro-optic phase shifter (36). Sets of input and output waveguides (18, 28) are connected to the beamsplitter and recombiner waveguides (20, 24) respectively. The input and output waveguides (18, 28) are periodically spaced at off-centre positions across the respective multi-mode waveguide transverse cross-section associated therewith. Radiation in any one of the input waveguides (18) is distributed between the relay waveguides (22) by virtue of modal dispersion in the beamsplitter waveguide (20). The phase shifters (36) apply a set of phase shifts to the distributed radiation. Modal dispersion in the recombiner waveguide (24) results in the phase shifted radiation providing a non-zero input to one or more of the output waveguides (28). Different sets of phase shifts provide for radi-ation in any one of the input waveguides (18) being transferred selectably to any one or more of the output waveguides (28), as required for selectable signal routing.

Title: Process for making polyvinyl chloride compositions having high heat distortion temperatures
Inventor: HUYNH-BA GIA
IPC: C08L/
Filed: 1992-03-06
Abstract: Heat distortion temperature of polyvinyl chloride compositions can be significantly increased above the heat distortion temperature of uncompounded polyvinyl chloride by preblending an imidized acrylic resin having a glass transition temperature above 140 ·C  with a third polymer melt-processable throughout the temperature range of 150-300 ·C under conditions where a two-phase blend is formed, wherein the third polymer forms the continuous phase and the imidized acrylic resin forms the dispersed phase and then melt-blending the two-phase blend with polyvinyl chloride at a temperature of 150-220 ·C to form a composition in which the imidized acrylic resin forms a substantially homogeneous blend with polyvinyl chloride. It also is possible to preblend imidized acrylic resin with a third polymer with which it is compatible, for example, another imidized acrylic resin having a sufficiently low glass transition temperature to lower the resulting glass transition temperature of the preblend below about 130 ·C, which then is blended with polyvinyl chloride.
